Question

ok in C++ i have a class assignment that i need to do and i dont fully understand how to work array's and strings. here is the assignment[ Create a process that accepts a specified string and presents an output in the form a string. Use arrays for the possible outputs and then present the output on screen. Meaning you should have outputs predefined and be calling the variables for the outputs]

Answer 1

it is supposed to accept a string
enter random words( 1,2,3)
-
-
-
outputs a variable
user arrays for the output strings

Answer 2

if someone could help it would be greatly appreciated

Answer 3

do you have sample input and output?

Answer 4

it has to be a word that leads to a definition

Answer 5

what is your high level plan?

Answer 6

if you could split the program into tasks, what are the tasks?

Answer 7

1 what is an array then the defintion
2 what is a character then a character
3 what is a string the the defintion
i belive that answers your question if it does not can you give me an example

Answer 8

this is all i have done on this assignment

#include <stdio.h>

int main (void)

{
char string [] = "arrays";
size_t i;

Answer 9

ok i have extended this a little bit im still not sure its right or if i am doing this correctly

#include <stdio.h>
#define SIZE 20

int main (void)

{
char string1 [] = "arrays";
char string2 [
size_t i;

if ( string1 = "grade" ){
puts( "A particular level of rank, quality, proficiency, intensity, or value" );
}
if ( string1 = "network" )

Answer 10

i dont think i need char string 2

Answer 11

a character is a datatype for storing a single letter.

Answer 12

it can store a, b, c, etc.

Answer 13

it is the size of a byte

Answer 14

an array is a group of variables. every variable in the group has the same data type. every variable in the group has an index, so you can access them individually

Answer 15

a string is a collection of characters. Usually you use an array to store the collection.

Answer 16

here is how i think it needs to look
#include <stdio.h>
#define SIZE 20

int main (void)

{
char string1 [SIZE];
size_t i;

printf("%s", "enter the words grade, network, or computer to find their definitions" );
scanf( "%10s", string1 );

if ( string1 = "grade" ){
puts( "A particular level of rank, quality, proficiency, intensity, or value" );
}
else if ( string1 = "network" ){
puts( "An arrangement of intersecting horizontal and vertical lines." );
}

Answer 17

Don't compare string with `string = "network"`. That won't work.
You'll need to compare them character by character.
You can use `strcmp()` or you can use a `for` loop.

Answer 18

ok so i need to use
for ( i = 0; i < SIZE && string1[ i ] != '\0'; ++i ) {
printf( "%c", string1 [ i ] );

Answer 19

At the beginning do something like:
```
char[] NETWORK = "network";
int equal;
```
When when you want to compare the string:
```
equal = true;
for (i = 0; string1[i] != '\0' && NETWORK[i] != '\0'; ++i) {
if (string1[i] != NETWORK[i]) {
equal = false;
}
}
if (equal) {
// they're equal!
}
```

Answer 20

Hmm, that code isn't correct.

Answer 21

```
equal = true;
for (i = 0; string1[i] != '\0' || NETWORK[i] != '\0'; ++i) {
if (string1[i] != NETWORK[i]) {
equal = false;
break;
}
}
if (string1[i] != NETWORK[i]) {
equal = false;
}
if (equal) {
// they're equal!
}
```

Answer 22

the best thing to do though, is to use `strcmp` from cstring library
